Use Primary Menu in Category

Hi,

I’ve been on a WP Config marathon so I apologise if I’m missing the obvious.

Right, I’ve configured a Primary Menu. In the menu I have a Parent Cat with Childs.

I’m losing the Primary in the Categories view.

Here’s a page with the primary menu.

When I go to a category, the menu is not displayed.

<?php $menuClass = 'nav';
			$menuID = 'top-menu';
			$primaryNav = '';
			if (function_exists('wp_nav_menu')) {
				$primaryNav = wp_nav_menu( array( 'theme_location' => 'Primary', 'container' => '', 'fallback_cb' => 'Primary', 'menu_class' => $menuClass, 'menu_id' => $menuID, 'echo' => false ) );
			};
			if ($primaryNav == '') { ?>
				<ul id="<?php echo esc_attr($menuID); ?>" class="<?php echo esc_attr($menuClass); ?>">
					<?php if (get_option('chameleon_home_link') == 'on') { ?>
						<li <?php if (is_home()) echo('class="current_page_item"') ?>><a href="<?php echo esc_url( home_url( '/' ) ); ?>"><?php esc_html_e('Home','Chameleon') ?></a></li>
					<?php }; ?>

					<?php show_page_menu($menuClass,false,false); ?>
					<?php show_categories_menu($menuClass,false); ?>
				</ul> <!-- end ul#nav -->
			<?php }
			else echo($primaryNav); ?>
